Yes, you can connect to a FTP server with examples.telnet.TelnetClientExample.java program. But you have to know very well about the FTP protocol to be able to change directory or download files.
Here is an example of using examples.telnet.TelnetClientExample.java program to connect to ietf.org FTP server:
